What is iBATIS?

iBATIS is a data mapping framework used in Java to map database records to objects in an application. It provides an easy-to-use data persistence mechanism that bridges the gap between relational databases and object-oriented programming.

The iBATIS framework is based on the Data Mapper pattern, which separates the data access code from the business logic code. It works by creating a mapping between the database tables and the Java objects using XML files. This mapping describes how the data should be extracted from the database and how it should be inserted, updated or deleted.

iBATIS offers several features that make it a popular choice for Java developers, including:

1. Lightweight: iBATIS is lightweight and does not require a lot of code to set up and use.

2. Flexible: It offers a flexible approach to data mapping, allowing developers to map data to objects in different ways.

3. Easy to learn: iBATIS is relatively easy to learn and use, even for developers who are new to Java.

4. High performance: iBATIS is designed to be fast and efficient, with minimal overhead.

5. Database independence: iBATIS works with a variety of databases, including Oracle, MySQL, PostgreSQL, and SQL Server.

iBATIS has been merged into the Apache MyBatis project, which provides a similar data mapping framework for Java and .NET. The latest version of iBATIS is iBATIS 3, which is now known as MyBatis 3.
